SOLID-STATE BATTERY AND METHOD FOR PRODUCING SOLID-STATE BATTERY

Abstract:

The present invention provides: a solid-state battery which is not susceptible to decrease of the discharging capacity even if charge and discharge are repeated; and a method for producing a solid-state battery, which enables the achievement of a good bonded interface between a solid electrolyte layer and a anode layer by a simple process. A solid-state battery 1 according to the present invention is provided with a cathode layer 20, a anode layer 30 and a solid electrolyte layer 40 that is arranged between the cathode layer 20 and the anode layer 30. The anode layer 30 is provided with an aluminum layer 31 that is in contact with the solid electrolyte layer 40, a lithium layer 32, and an aluminum-lithium alloy layer 33 that is arranged between the aluminum layer 31 and the lithium layer 32.
